Description
Technical field:
The present invention relates to a kind of bearing double-side dustproof lid technique for riveting and mould.
Background technique:
Be with dust-proof cap-type stuffing box bearing to be widely used in many dirt in various machinery support, many befouling environment, or prevent pre-fill seborrhea from going out according to different application operating mode at the special lubricating grease of the pre-filling of Bearing inner.Bearing two sides is with dust cover, and dust cover is fixed by special riveting mould and bearing outer ring.
In prior art, the usual corresponding riveted in the left and right sides of two sides band dust-proof cap-type stuffing box bearing has left and right two dust covers, its concrete technique for riveting comprises the following two kinds, mode one: riveting die is made up of upper stamping die, base, axle, and staking step generally includes 1) on riveting die, lay bearing; 2) riveted dust cover; 3) take out bearing and overturn; 4) bearing after upset is placed on riveting die again; 5) another dust cover of riveted; 6) tear open and move bearing.Mode two: riveting die is only made up of upper stamping die, during riveted, bearing is non-treats that the one side of riveting dust cover directly lies on press bench, punch die is placed in the top that riveting dust cover one side treated by bearing, after a complete dust cover of riveted of the bearing relative with punch die, upset bearing, then another dust cover of riveting.
There is following defect in the technique for riveting of aforesaid way one: bearing is twice disassemble or assemble on mould, and efficiency is low.Then there is following defect in the technique for riveting of mode two: punch die is directly placed in the top that riveting dust cover one side treated by bearing, and mould only by dust cover circular arc crimping location, easily occurs the phenomenons such as riveted bias, inclination; Meanwhile, bearing is directly placed on press bench, and when cycle surface is protruded in bearing inner race lower end surface, outer ring place vacant state, riveted process riveted power reaches inner ring raceway from outer ring raceway through rolling element, produces impact injury to bearing.
Summary of the invention:
The object of the present invention is to provide a kind of bearing double-side dustproof lid riveting die, its structure is simple, can make two dust cover uniform stresseds and once be riveting on bearing simultaneously, raising the efficiency more than 60%.
A kind of bearing double-side dustproof lid riveting die, it is characterized in that: comprise worktable, be located on worktable can the guiding module post that mate concentric on bearing inner race, concentric locking collar is located at the outer and lower stamping die offseted with worktable of guiding module post, concentric locking collar is located at guiding module post outward also can along the upper stamping die of the upper and lower slippage of guiding module post, and the pressure head be positioned at above stamping die, described lower stamping die is convex is provided with the annular riveting mouth that can act on described bearing one dust cover, described upper stamping die is convexly equipped with the annular riveting mouth that can act on described another dust cover of bearing downwards, pressure head can move down and pushing tow on stamping die along the downward slippage of guiding module post, make the annular riveting mouth of stamping die and lower stamping die can in pushes against sleeve is located at the bearing on guiding module post respectively simultaneously two dust cover crimpings the simultaneously riveting of two dust covers being entered dustproof groove that bearing outer ring is offered.
The mould structure of the present invention is simple, and its upper and lower stamping die can make two dust cover uniform stresseds and once be riveting in dustproof groove that bearing outer ring is offered simultaneously, without the need to twice disassemble or assemble, raises the efficiency more than 60%.
The present invention improves by following scheme:
The present invention also comprises dust cover riveted depth adjustment, and this dust cover riveted depth adjustment to be located on described worktable and to be positioned at the side of described guiding module post and to be positioned at the below of described pressure head.Can according to bearing size size adjustment the height of dust cover riveted depth adjustment, realize the restriction of upper and lower punch die riveted axial depth, finally determine the dust cover riveted degree of depth.
Described dust cover riveted depth adjustment comprises an adjustment seat offering interior threaded hole, matches and can screw the adjusting screw rod of adjustment up and down along interior threaded hole and be located at the locking nut coordinated in adjustment seat and with adjusting screw rod with adjustment seat interior threaded hole.Structure is simple, easy to adjust.
The taper pushing tow face that annular riveting mouth described above has can be made the crimping of dust cover bend, rise outward.Structure is simple, can fast, facilitate in the dustproof groove that dust cover riveting entered bearing outer ring is offered.
Another object of the present invention is to provide a kind of bearing double-side dustproof lid a technique for riveting, this technique can make two dust cover uniform stresseds and once be riveting on bearing simultaneously, raises the efficiency more than 60%.
A kind of bearing double-side dustproof lid technique for riveting, is characterized in that comprising the steps:
1) two dust covers of bearing are preset in the dustproof groove being opened in bearing two end faces;
2) on the guiding module post bearing concentric locking collar presetting two dust covers being located at riveting die described above and between upper stamping die and lower stamping die;
3) pressure head move down and pushing tow on stamping die along the downward slippage of guiding module post, make the annular riveting mouth of stamping die and lower stamping die simultaneously respectively pushing be located at two dust covers of bearing on guiding module post, the crimping of two dust covers is bent, to rise outward and riveting simultaneously enters in dustproof groove that bearing outer ring is offered;
4) tear open and move bearing.
The technique of the present invention, can make two dust cover uniform stresseds and once be riveting on bearing simultaneously, raising the efficiency more than 60%.
